Perimeter of a Pentagon The perimeter of a pentagon is the total length of all its sides. A pentagon, by definition, is a polygon with five sides, and the perimeter is simply the sum of the lengths of these sides. The method for calculating the perimeter can vary depending on whether the pentagon is regular or irregular. Perimeter of a Regular Pentagon A regular pentagon is a polygon where all five sides are of equal length. This symmetry makes it easier to calculate the perimeter. Formula for the Perimeter of a Regular Pentagon For a regular pentagon, the perimeter P P can be calculated using the following simple formula: P = 5 × s P = 5 \times s Where: P P is the perimeter. s s is the length of one side of the pentagon. Since all sides are equal in a regular pentagon, the perimeter is simply five times the length of one side. If you know the side length, you can multiply it by five to find the total perimeter.
